The Research Of The Texture Created In Computer Graphics

The rendering of reality graphics as an important part of the computer graphics,it synthetically using math, physics, computer science and the other science knowledge creates reality graphics like the photos at the computer graphy equipment.This work started corresponding working from the1960s,to 1980s,as the improving of quality of the vision equipment,which may already make out the exquisite and colorful reality graphics.As the geometry modeling,the technology of entity modeling,the arithmetic speeding eliminant,,the technology of body rendering,the model of entirely illumination,the method of radiated degree and the development of the endlessly inproved technology of the ray track,making the reality graphics quality have a huge enhance;using for rendering peculiar form object in the particle subsystem,the texture thchnology ect.provids the more colorful reality graphics.Moreover,lately,the technology of the reality graphics creating basing on the graphics rendering technology and the point rendering also has the better development.With the fast development of the modern science technology,vs the reality graphics technology put forward higher and higher demand,studing the technology of the texture-mapping has the more important meaning.In the process of generating 3D sense of reality graphics with computer,besides simulating the natural lighting-effect by the lighting-model,we also need to make it more close to the natural scenery by simulating the detail of surface of object.The texture in the computer graphics may classify for color texture, geometry texture and process texture.The color texture lies on the optics property on the object surface;the geometry texture relates on the microcosmic geometry figure on the object surface;the process texture is directly defined using the texture function in the 3D space. These are one of the important subjects of computer graphics,which get people's attention at all times.This paper sums up the above three kinds of texture mapping technology,about the part texture mapping arithmetic realizes.Thereinto, color texture is mainly working on texture mapping arithmetic,worked out the texture mapping vs differently parameter surface and presents the result.In the process of studing geometry texture. This paper proposes an approach of geometry texture based on OpenGL, this approach chose random function and trigonometric function as the harass function by research of one kind of geometry texture composing rule.The approach produces corresponding geometry texture through disturbing the scenery surface vector.Simulation results show it is effective.In the explaination of the process texture,the paper mainly studing the application of wood texture function at the plane,the cube and by the texture color of wood texture annual ring diameter processes linearity interpolating,which make the change of these wood texture annual ring color has the transition,the more vividly simulates the reality wood texture.The arithmetic is carried out in this paper basing on VC++ and OpenGL,and presents the berrer result.
